Visa: Possible Data Breach

The statement came in response to a News.com inquiry related to customers whose Visa debit cards had been put on fraud watch or deactivated due to a security breach. The customers include a San Francisco Bay Area man whose Wells Fargo-issued card had been deactivated and a couple in Ohio whose card was placed on a watch.

In its statement issued Saturday, Visa said that after it learned "of the compromise, Visa quickly alerted the affected financial institutions to protect consumers through independent fraud monitoring and, if needed, reissuing cards."
